Are all birds and mammals endothermic?

Answer 1

Yes. All mammals have a backbone, and are therefore vertebrate. And all living mammals are endothermic, which is the scientific term for warm-blooded, meaning they generate their own body heat rather than relying on the environment.

Answer 2

Yes - they always require an external heat source to raise their bodies to a 'working' temperature. The heat source would normally be the sun - but us herpetologists normally use artificial heat sources to maintain the correct temperature range.

Answer 3

No. They are ectothermic, not endothermic. All reptiles and amphibians are ectothermic, which is commonly referred to as 'cold-blooded'. Their body temperature is dependent on external environmental conditions.

Answer 4

All mammals are warm blooded.

Mammals and birds use a lot of energy maintaining a constant body temperature.

Answer 5

No. Snakes and reptiles are vertebrates, but are exothermic (cold-blooded) and require the warmth of the sun.

Answer 6

yes they are all endotherms and are vertebates

Answer 7

Yes. All mammals and birds are endothermic because they can maintain their own body temperature. The term 'endothermic' is the biological term for an animal that is warm-blooded.
